All Implemented Interfaces:

public class CustomDateEditor
extends java.beans.PropertyEditorSupport

PropertyEditor for Date, supporting a custom DateFormat.

This is not meant to be used as system PropertyEditor but rather as locale-specific date editor within custom controller code, to parse user-entered date strings into Date properties of beans, and render them in the UI form.

In web MVC code, this editor will typically be registered with binder.registerCustomEditor calls in an implementation of BaseCommandController's initBinder method.
